Beta version of the ONEFlux data product

ONEFlux processing produces gap-filled, partitioned flux/met data that are fully consistent with the FLUXNET2015 data product. FLUXNET included data through 2014. Read more about ONEFlux codes

We are making available a beta ONEFlux product with data through 2018 for a limited number of AmeriFlux sites in advance of a larger release in 2020. The purpose of this early release is to allow users to play with the data and develop analysis capabilities. As a Beta product, we expect there will be data revisions before the final data product is released. Please use the non-Beta data release (Spring 2020) for publication research.

These data are shared with the standard AmeriFlux data policy. Downloading data requires an AmeriFlux or FLUXNET account. Click to create a new account.

You can generate this information and make maps for any group of AmeriFlux sites using SITE SETS!


About ONEFlux

ONEFlux (Open Network-Enabled Flux processing pipeline) is an eddy covariance data processing codes package. This open-source code set consolidates multiple computations to process half-hourly (or hourly) flux inputs in an automatic fashion, including friction-velocity-threshold estimation methods and filtering, gap-filling of micrometeorological and flux variables, partitioning of CO2 fluxes into ecosystem respiration and gross primary production, uncertainty estimates, and more.

The code is compatible with the version used to create the FLUXNET2015 dataset; it has been tested against for 100% of the FLUXNET2015 sites for the nighttime partitioning method and 90% of the sites for daytime partitioning method.

ONEFlux code is available under a BSD open-source license on this GitHub repository:

ONEFlux was spearheaded by the AmeriFlux and European Cluster central offices. The two groups jointly developed common codes and procedures that are the basis for the ONEFlux collection. In addition, many regional networks and colleagues from around the world contributed. See the Contributors section in the code repository.

We are not able to offer any form of support for using the software. Please see a list of caveats and known limitations in the GitHub repository.
